FRAM E-JOINT.

SPECIFICATION forming part of Letters Patent No. 714,402, dated November 25, 1902.

Application tiled April 28, 1902.

To @ZZ whom, it may concer/'71,:

Be it known that we, JAMES H. SAGER and GEORGE D. GREEN, citizens of the United States, and residents of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Frame-Joints, of which the following is a specification.

This invention relates to fra1ne-joints; and it consists of devices hereinafter described and claimed. Its object is to produce a simple and strong construction.

The novel features of the invention are set forth in the specification and claims.

In the drawings, Figure l is a plan view of the joint as applied to the crank-hanger of a bicycle. Fig. 2 is a section on the line 2 2 of Fig. l. Fig. 3 is a side view of said joint, and

Fig` i is a perspective of one section ofthe joint.

The joint is represented in the drawings as constituting a connection between a plate A, that is curved in the example shown, and a section B, the latter comprising sockets B and B2, to which in the form shown the central brace and the pillar-post of a safety-bicycle frame are to be attached, respectively. The plate A is adapted to fit upon the top of the pedal-shaft barrel A' of a bicycle-frame, to which it is brazed or otherwise lirnlly secured. By this means the hinged-joint connection is provided at the crank-hanger between the front and rear sections of the bicycle-frame, which is essential to the operation of certain spring-fran`1es for bicycles. Inasmnch as the plate A may be attached to the hanger A at different points on its surface, the saine joint may be used with frames differing with respect to the angle between the seat-post and rear braces in their normal positions.

The hinged joint is constructed as follows: Parallel slots a ware made in the plate A, thatare adapted to receive lugs C C. These lugs are represented as larger at their bases than said slots, respectively, so that they cannot be drawn out through said slots. At each end of said slots ears or tongues ct d' are turned np from said plate in the manner shown by dotted lines in Fig. 2. Notches c c Serial No. 105,009. (No model.)

are cut in each side of' each lug C, respectively, to receive the ears a. ct', as shown in cross-section in Fig. 2. After the lugs have been inserted through the said slots in the plate A the ears a' a on the plate A are forced down upon said lugs. In the construction shown the ears u. a. are forced into the notches or grooves c c in the sides of the lugs, so that said ears will lie beneath the shoulders c'c and resist the tendency to force the lugs back through the slots in the plate A.

It the lugs are larger at their bases than the slots a a, in the plate A, so that the lugs cannot pass upward through said slots, said lugs will be locked to the plateA by the fact of attachment of said plate to that part of the frame to which the plate is attached and without the necessity of using the ears described above. So, too, though the lugs are small enough throughout their length to pass entirely through the slots in the plate A, the ears d a will, neverthess, lock them to the plate if forced down upon some part of said lug and below shoulders thereon after the manner shown, provided said ears are large enough and strong enough to resist the strain to which they will be subjected. In either case brazing the parts together strengthens these connections. An importantfeature of the invention is the construction of the said section B. As stated above, this is the hangercluster of a safety-bicycle frame and cornprises the tubular sockets for the lower ends of two frame members, such asthe central brace and pillar-post. This cluster is stamped from a single piece of sheet steel (see Fig. 4) and is accordingly made very easily and cheaply. It consists ofthe two tubular sockets B B2, each open at both ends and slotted longitudinally, and the hollow arched connecting portion ZJ integral with said two sockets.

The lugs C C are pivotally connected with the section B by means of a bolt E, which passes through perforations c2 c2 in said lugs C C and through perforations h2 in the opposite walls of the hollow arched portion b.

A tube D, adapted to contain the pivotal y supporting-bolt E, is first placed inside the section B,- so that its ends register with the opposite perforations h2 therein, and within to said section and adapted to lock said lugs to said section; and means for connecting another section of said frame to said lugs; substantially as described.

2. In a frame-joint, the combination with one section of the frame, of lugs; ears integral with said section and adapted to lock said lugs to said section; and means for pivotally connecting another section of said frame with said lugs; substantially as described.

3. In a frame-joint, the combination with one section of the frame having slots therein, of lugs adapted to enter said slots; means for locking said lugs within said slots; and a connection between said lugs and another section of `said frame; substantially as described.

4. In a frame-joint, the combination with one section of the frame having slots therein, of lugs adapted to enter said slots; ears attached to said section whereby said lugs are locked to said section; and a pivotal connection between said lugs and another section of said frame, substantially as described.

5. In a frame-joint, the combination with one section of the frame having slots therein, of lugs adapted to enter said slots but larger at their bases than said slots; means for locking said lugs within said slots; and a connection between said lugs and another section of said frame, substantially as described.

(l. In a frame-joint, the combination with one section of the frame having slots therein, of lugs adapted to enter said slots but larger at their bases than said slots; ears attached to said section and adapted to lock said lugs to said section; and a pivotal connection between said lugs and another section of said frame; substantially as described.

7. In a frame-joint, the combination with the section A of the frame having slots therein and the ears Ct', ct; the lugs C, C; and a pivotal connection between said lugs and another section of the frame; substantially as described.

8. In a frame-joint, the combination with the section A, of the frame having slots therein and ears a', a; the lugs C, C, having notches for said ears; and pivotal connections between said lugs and another section of the frame, substantially as described.

9. In a frame-joint, the combination with the section A of the frame having slots therein, of the ears a', a integral with said section and at the ends of said slots; the lugs C, C,

larger at their bases than said slots and having notches in which said ears rest; and a pivotal connection between said lugs and another section of the frame; substantially as described.

l0. A hanger-cluster having tubular sockets for the frame-pieces of a metal-frame vehicle; a hollow portion connecting said sockets and integral therewith; and a tubular bolt-bearing transversely set in said hollow portion and connecting opposite walls thereof; substantially as described.

1l. A hanger-cluster having tubular sockets for the frame-pieces of a metal-frame vehicle, said tubular sockets being slotted longitudinally; a hollow portion connecting said sockets and integral therewith; and a tubular bolt-bearing transversely set in said hollow portion and connecting opposite walls thereof; substantially as described.

l2. A hanger-cluster having tubular sockets for the frame-pieces of a metal-frame vehicle; a hollow portion connecting said sockets andintegral therewith; and atubular boltbearing set in said hollow portion and connecting opposite walls thereof and consisting of two tubes one inside the other, the inner tube passing through perforations in the walls of said hollow portion and the outer tube resting against the inner surfaces of said opposite walls; substantially as described.

13. A hanger-cluster having tubular sockets for the frame-pieces of a metal-frame vehicle, said tubular sockets being slotted longitudinally; a hollow portion connecting said sockets and integral therewith; and a tubular bolt-bearing set in said hollow portion and connecting opposite walls thereof, and consisting of two tubes one inside the other, the inner tube passing through perforations in the walls of said hollow portion and the outer tube resting against the inner surfaces of said opposite walls; substantially as described.
